7 This invention relates to a device for spray ing upholstered furnitureand more particularly to a system of pipes permanently concealed'in theupholstery of furniture and having a series of ports through which afluid, for the extermination of moths andthe like,"is forced and sprayedinto the upholstery. i

Upholsteredfurniture and particularly upholstered furniturewhich iscovered with mohair is particularly subject to attacks of moths whichdestroy portions of the covering and necessitate recovering of theentire piece "of furniture in view of the fact that it is diflicult tomatch particular portions of the covering. Heretofore it has beenattempted to spray furniture with a moth exterminating fluid from theexterior of the same. The moths, however, get into the breaks betweenthe diiferent upholstered surfaces and make it extremely difficult toreach them by'a surface spraying. Ihe present invention, therefore,proposes a system of pipes which are concealed within the upholstery andare provided with a series of ports the entire length of the same,whereby the moth extermin ating fluid is sprayed into those parts'ofthefurniture where the moths are most likely to lodge, and also completelyspray the upholstery from the interior thereof, thereby permeating theentire upholstering with the fumes of the moth exterminating fluid andalso retaining the fumes within the upholstering for a considerablelength of time. By this means only an occasional spraying is required.

One of the ob'ects of this invention is to provide a device of thischaracter which is completely concealed within the upholstery when notin use and does not interfere with the comfortable-use of the piece offurniture. A further object is to provide such a device which canreadily and quickly be brought into operative position and the sprayingof the furniture accomplished thor- Q I oughlyand in a short time.

Afurther aim of this invention is to provide SllChttCl'GVltCG Wl1lCllhas a reservoir for the storage of the. moth exterminating fluid 80 andin which it is only necessary to create" an air pressure on the top ofthe reservoir to force apart of thefluid contained therein through thepipe system toeifect a spraying of the upholstering.

A stillfurtherpurpose to so organize and arrange the pipe systemthat thespray will be discharged at the places in the upholstering where themothsare most likely to lodge and lay their eggs.

Other aims are to provide a device which is light, compact andinexpensive and which. can readily be installed in furniture of standarddesign without substantial alteration thereof.

Figure 6 shows a pump which is adapted for use in connection with thepresent inven-- tion, this pumpbeing actuated through movement derivedfrom the persons'itting down in the chair for spraying a quantity of themoth exterminating fluid into the upholsterin The present invention isshown as applied to an overstuffed arm chair which in general comprisesan uphostered spring supported seat an upholstered back 11; and twoupholstered arms 12, the upholstering being arranged to provide breaks13 between the arms and the seat and a break let between the back andthe seat.

The chair frame which supports the upholstering and also carries thesystem of pipes and the reservoir of the present invention, as bestshown in Figure 1, comprises two front posts 15, 15; two rear posts 16,16; a front rail 1?, connecting the front posts; a back rail 18connecting the lower ends of the back posts 16; side rails 19, 19,connecting the lower ends of the corresponding front and back posts; aback rail 20 connecting theupper ends of the back posts; a pair ofarmrails 21, 21, connecting the upper ends of the corresponding frontand back posts; upholstering rails 22, 22, connecting the correspondingfront and back posts and arranged between the arm rails 21 and the siderails 19 thereof; vertical bars 23, 23, extending between the upper andlower backrai's 20 and 19; and a horizontal back upholstering rail 2between the vertical bars 23.

' The seat of the chair may be upholstered in any well-known manner, andas shown in Figures 2 and 3, webbing 25 is stretched between the lowerfront, side, and back rails and is secured to the underside thereof. Thewebbing supports a group of springs 26'which are housed within a burlapcasing 27 which casing is suitably secured at its edges to the webbing.This casing is covered in the usual manner with a fibrous stuffing 28,such as moss, hair or the like and the stuffing is enclosed by thecover29. The cover 29 for the seat, is secured at its front to the front rail17 and at its sides to the side rails 19, as best shown in Figure 3. Atits rear the cover 29 extends down and is secured to the back rail '18.At its center, as best shown in Figure 2, an opening 30 is left in thecentral part of the cover 29, this opening receiving the storage reser:voir 31 of the fiuid'systein.

Across theback of the frame a piece of webbing 32 is stretched, whichwebbing supports the group of back springs 33. These back springs areenclosed by a burlap casing 34, which is secured at its edges to theback rails 18 and 20 and the vertical bars 23. This casing is covered bystuffing 35 and the studing is coveredby'the back cover 36. The backcover 36 is secured at its lower end to the lower back rail .19 andextends over and is secured at its upper end to the rear side of theupper back rail 20. At its sides this back cover 36 is secured to theouter side of the vertical bars 23. as best shown in Figure 4.

The webbing 32 is covered by a piece of burlap 37, and over this burlapis arranged a sheet 38 of felted material, this felted material beingcovered by the back cover 36 which is extended over the rear side of theback and is secured at its lower end to the lower back rail 18.

Each of the arms, as best shown in Figures 3 and 4 is upholstered in thefollowing manner:

On the upper side of the arm rails 21 is arranged a longitudinal row ofsprings 39 which are housed in a burlap casing 40. Between the arm rail21 and the upholstering rail 22 a piece 41 of burlap is stretched andover this piece of burlap 11 and the burlap housin 40 for the springs isarranged a mass of stufiin 12, which ismolded to conform to the desiredshape of the arms. The stuffing is covered by the arm cover 43 which issecured at its lower ends to the side rail 19 and extendscompletelyaround the arm. The stufiing 42 extends around the undersideof the roll or bulge of the arm, and to prevent its inward displacementa piece of .burlap 44 is secured to the arm rail 21 and at its lower endis secured to the inner side of the cover 43. I

It will, therefore, be apparent that the above construction provides anupholstered chair which has an interior hollow compartment 15 in theback, an interior compartment 46 in each of the arms and theupholstering is arranged to provide the breaks 13 and 14 around theseat, which permits things to be inserted between the seat and the armsand thoback. thereby completely concealing the same within the breaksand 14. The reservoir 31 which is adapted to contain a supply of themoth exterminating'fiuid sufficient for a number of sprays of the pieceof furniture is secured to the front side of the lower backrail 18.by-means ofa strap 47. This reservoir inc? udes a vertical cylindricalbody which isclosed at its upper and lower ends by heads 18 and 19. Inthe upper head v4E8 is screwed a short sectionof pipe 4 91, in the upperend. of which is arranged a swivel elbow 50. Extending laterally fromthis swivel elbow 50 is a filling pipe 51having an elbow 52 at its outerend, which elbow opensupwardly.

The filling pipe 51 is arranged to swing rearwardlyinto the break Hbetween the back 11 and the seat 10 andibe completely concealed withinthis break. When it is desired to either fill the reservoir 31 with themoth exterminating fluid or to create an air pressure in the upper partof the reservoir the person spraying the chair reaches in the break 14,pulls the filling pipe 51 out, and pours a suitable quantity of mothexterminating fluid into the reservoir through this filling pipe. Shethereafter attaches a suitable air pump (not shown) to the filling elbow52 and forces air into the upper end of the reservoir. Such a pumpma-yibe of a size which can be conveniently and readily inserted intothe break 14 and be stored therein in a position in which it iscompletely concealed and does not in any way afiect the comfort of thechair.

' Ashort section of pipe 53 issecured on each side of thereservoir 31 atthe lower end thereof and each connects with a vertical pipe 54: whichextends up through an opening in the back upholstering rail 24, as bestshown in Figure 1. At its upper end each of these vertical pipes 5 1 isconnected-to a hoI-izontal. 1'ear pipe 55 which extends outwardlytherefrom and is arranged in front of the vertical bars 28. Each ofthese pipes 55 have a T-coupling 56 to which is secured a vertical pipe57 which extends upwardly between the vertical bar 23 and thecorresponding back post16. The upper end of this vertical pipeisclosedby a cap 58. To the other end of each 'of the T-couplings'56 is secureda short section of pipe 59 which is connected by an elbow 60 with alongitudinal extending pipe 61, the outer end of which is capped. Thesepipes 61 are arranged within the interior compartment 46 of the arms andthe pipes 55 are arranged in the interior compartment 45 of the back.Each of the pipes 6.1 and 55 are provided on their upper and lower sideswith a series of ports 62, which series extend the entire length ofthese pipes and permit the fluid under pressure in these pipes to escapetherefrom in fine streams which completely saturate the interior of theupholster ing of both the armsand the back.

In a similar manner the vertical pipes 57 are provided on their frontand rear sides with a series of ports which spray the moth exterminatingfluid into the break between the back and the arms, as best shown inFigure 4. I

It will, therefore, be apparent that when an air pressure is created inthe upper part of the reservoir 31 the fluid is forced through thesystem of pipes just described and is sprayed into the interior of thearms and the back and is also sprayed in the break between the arms andthe back. By this means the fluid is sprayed at the places where mothsare lodge, particularly in the breaks between the different parts of theupholstering. Moreover after being sprayed the fumes of theexterminating fluid are retained within the upholstering for a veryconsiderable length of time and only infrequent use ofthe device istherefore necessary to completely insure the extermination of moths fromthe piece of furniture.

In Figure 5 is shown a modification of the invention, shown in Figures1-4. In this modification a reservoir and piping system is providedwhich is made and sold as a unit and i's-adapted to be inserted inupholstered.

most likely to furniture which-is alreadyvfabricatedor in actualuse. Inthis construction the reservoir 31 is arranged horizontally and is ofcomparatively small diameter therebyv permitting it to be readilyinserted int-he break 14 between the back and the seat of the chair. Thefilling pipe 51 is similarly c011- nected by an :elbow swivel with ashort pipe section l9 communicating with the upper endof the reservoir31 as in the preferred construction andswings in and out of the break llas described.

The pipes each connect with the end of the reservoir 31 through inclinedpipes 54 arranged at the lower end thereof and at its outer end eachpipe 55 is connected by. an elbow with the longitudinal pipe 61 whichex.-

tends along the corresponding arm. By this means a reservoir with aU-shaped system of piping is provided and the complete unit can beinserted into the breaks 13 and 14 between the seat 10 and theback 11and arms 12. The pipes 55 and 61 in this construction are provided witha series of ports which spray the respective break. The operation ofthis form of-the invention. issimilar to the operation mothexterminating fluid into the or system shown in the preferred form. In

7 order to permit of adapting the pipe system to d'iiferent sizes andtypes of furniture a coupling is'provided in the pipe 55. By

this means if this form the invention is being app-lied to davenports,one section of. the pipe 55 can be cut tothe desired length andeeupled'to the other section by means of the I coupling 80. a

If it is desired to providemeans whereby the weight of a person. sittingdown in the chair will operate to. cause a small amount of mothexterminating fluid to be sprayed into the upholstering, a small .airpump 70 may be housed within the seat 10, the casing of this pump beingsecured in anysuitable manner to the webbing-25 and the piston rodthereof'may be secured to the underside of a burlap casing 27. Theoutlet 71 for this pump may be connected with the reservoir 31 byme-ansof a flexible conduit 72'or in any other suitable manner. By this meanswhenever a person sits down in the chair he moves the piston rod of thepump 7 O downwardly and creates a pressure in the upper part ofthe'reservoir 31 which operates to force a small quantity of the mothexterminating fluid through the piping system and into the upholstering.

This pump is more particularly adapted for the form of the inventionshown in Fig ures ll inasmuch as it is necessary to build it into thechair or piece of furniture while it is being upholstered. It is obviousthat while the present invention has been shown and described withreference to an overstuffed. arm chair that it .is equally applica- Ivariously organized to suit different requirements without departingfrom the scope of the invention, as set forth in the appended claims.

As a whole this invention provides a very simple and inexpensive systemof pipes whereby moth exterminating fluid can be effectively sprayedinto the interior of the upholstering and thereby permeate the entirepiece of furniture. It'is also convenient to use and when not in use iscompletely concealed in the upholstering and does not in any wayinterfere with the comfort of the piece of furniture.
